IP69K vs IP67: What Is the Difference?

Both ratings mean the enclosure is dust-tight, but they test water in different ways. IP67 covers temporary immersion, up to 1 m deep for 30 minutes. IP69K covers close-range, high-pressure, high-temperature water jets, like those used in wash-downs. Passing one does not mean passing the other, so equipment that faces both is tested to both.

01

The Short Answer

In an IP69K test, hot water is sprayed from about 10 to 15 cm away at several angles while the device turns. A seal that survives being submerged may still be forced open by that jet, and a seal built for jets may still let water creep in under pressure of immersion, which is why the two are tested separately.

    Food and beverage lines IP69K, for daily high-pressure, hot wash-downs.
  • //
    Outdoor and submersible kit IP67 or IP68, for rain, puddles and immersion.
  • //
    Vehicles IP69K where trucks or machines are pressure-washed.
  • //
